During electrophilic aromatic substitution, resonance-stabilized cation intermediates are formed. Groups already present on the benzene ring can directly ortho/para further stabilize this intermediate by participating in the resonance delocalization of the positive charge.
contributor that shows this group actively participating in the charge delocalization
